VALVE-OPERATING MECHANISIVI.

SPECIFICATON forming part of Letters Patent No. 364,695, dated June 14,1887.

Applicationl tiled January B1, 1587.

To all whom, it may concern:

Be it known that I, GEORGE T. WILsON, of Boston, in the county of Suffolk and, State of Massachusetts, have invented a :new and useful Improvement in Valve-Operating Mechanisms, of which the following is a specification.

My invention relates to Yvalve mechanism for so controlling the passage of water to a water-closet orv other iiXtu re required to be ushed asto prevent agreateramoi1nt of water passing to the water-closet or other fixture than is necessary to flush the same.

In my invention I employ alever connected at one end with the valve and at theother end with a ratchet-wheel, and a wheel provided with means to operate it and carrying a weight and pawl, said `pawl engaging with the ratchetwheel when the pawl-carrying wheel is operated, and causing the ratchet-wheel to rotate when the pawl-carrying wheel is rotated by said weight, whereby the end of the lever connected with the ratchet-wheel is depressed, lifting thereby the end of the lever with which the valve is connected and causing the valve to rise, the pawl, when the valve is thus raised, being thrown out of gear with the ratchetwheel, and the lever allowed to return to place and the valve to close. As a means to make the lever return to place slowly, and thus make the valve Slowclosing, a piston, connected with the e'nd ofthe lever with which the ratchetwheel'is connected, may be used to act as a drag upon the lever when'returning to place; but this means of making the valve slow-closing formsnopart of my present invention.

In the drawings, Figure l shows myinvention in elevation, the tank and outlet-pipe in section, the handle H pulled down, the pawl engaged with the ratchet-wh eel, and the valve closed. The parts shownin broken lines indicate the position of those parts at the instant Fig. 2 shows a top plan of my inven- 'serial No. 225.976. (No model.)

valve-operating` mechanism looking toward the side opposite to that shown in Fig. 1.

L is the lever attached to the tank T at Fm the fulcrum of the lever. The lever is connected at its weighted end by the chain c3 with the valve V, and connected at its other end by the chain c with the grooved ratchet-wheel R', which latter wheel has the stop-screw s.

'G is the pawl-carrying wheel, grooved and having an ear, e, to which is pivoted the pawl P at p. The ear c has the pin i, to prevent the pawl from upsetting and failing to engage with the ratchet-wheel. The pawl-carrying wheel G'has the vscrew-stop s', and a weight, W, hung from it by the chain c', and is connected with the operating-handle H by the chain c2.

B is a bracket fastened to the tank T, supporting the cylinder C, by means of the screws ff, which pass loosely through Vholes in the bracket, that the cylinder may tilt when the lever moves. the ratchet-wheel R and the pawl-carrying wheel G by means of the axis r, as shown, and

is provided with au arm, a, which passes under the pawl-carrying wheel G, serving to stop the pawl-carrying wheel, and to throw the pawl. out of gear with the ratchet-wheel when the pawl-carrying wheel is rotated by the weight W.

C is a. cylinder having a hole, 711, for the pas sage of air, in which works a piston, P', provided with a valve, u, for the passage of air, and connected by the piston-rod-R and link l withjthe end ofthelever with which the ratchetwheel is connected to act as a drag upon the lever when closing.

The operation is as follows: The handle H is drawn down and the pawl-carrying wheel rotated thereby, and the weight W lifted to the 4posit-ions shown in Fig. 1. When the handle is released, the weight W eaulses the pawl-carrying wheel to rotate back to place, and its pawl l?, engaged with the ratchet-wheel, to carry the ratchet-wheel to the position shown in Fig. 3, depressing thereby the end ofthe lever with which the ratchet-wheel is connected and lifting the end of -the lever with which the valve is connected, causing the valve to rise and allow the water to flow to the water-closet The bracket B further supports 4 IOC) or other fixture to be flushed. The pawbcui rying wheel, still rotating back to place,strikcs the arm a, and is stopped thereby, and the puwl l), also striking the urm a, is thrown ont of gen1-with the ratchet-wheel. The lever, pawl, and weight are then in the positions shownin broken lines in Fig. l and the valve wide open. The weighted cncl of the lever and the force exerted by the valve then causes the lever 1o to return to place and to return the ratchetother end with a ratchet-wheel, and having another wheel provided with means to operate it and carrying u weight and puwl, said pawl engaging with said ratchet-wheel to cause the valve to open, and being thrown out of gear with it to allow the Valve to close, whereby the valve is opened butonce and a, single flushing caused, all substantially as described, for the purpose specified.
